高空飞翔游乐设施的地基基础作为构筑物承载的核心部分,合理设计尤显重要,直接影响到整个结构运营的安全性、稳定性和耐久性。首先根据相关规范及其构筑物的高度确定基础的埋置深度,其次根据地表以上结构传递的荷载特点及其大小确定基础的形状和尺寸,最后采用FLAC3D软件建模,分析最不利工况下地基的承载力及基础的沉降,验证地基基础设计的正确性。特别是在处理施加在地基基础上的荷载时,将上部结构传递的力矩转换成分布力,其中拉力以及水平剪力作用在地脚螺栓上,压力作用在钢筋混凝土上。计算结果表明基础设计满足规范要求。
As the core part of the structure bearing, the reasonable foundation design of the ground-based rides of the high-altitude flying rides has a significant impact on the safety, stability and durability of the entire structure operation. First of all, the depth of embedment is determined according to the relevant norms and the height of the structure. Secondly, the shape and size of the foundation are determined according to the load characteristics and the size of the structure above the earth’s surface. Finally, FLAC3D software is used to analyze the foundation under the most unfavorable conditions Bearing capacity and foundation settlement to verify the correctness of foundation design. In particular, when dealing with loads applied to foundations, the moments transmitted by the superstructure are converted into distributed forces, where tensile forces and horizontal shear forces act on the anchor bolts and the pressure acts on the reinforced concrete. The results show that the basic design to meet the regulatory requirements.
